"And I did not create the jinn and mankind except to worship Me" (51:56). Liya'buduni (to worship) Me means liya'rifuni (to know Me). Yet the Divine Essence is absolutely transcendent. How can the knowledge of Allah be the reason and purpose of our creation when the Divine Essence cannot be approached? "Who Knows Himself Knows His Lord" is the door and its key is "Prostrate and draw near [to Allah]" (96:19).
